自适应柔性叶片风力机气动性能模拟优化

Aerodynamic Performance Simulation and Optimization of the Adaptive Vertical Axis Wind Turbine

在传统Savonius风力机基础上,提出并设计了一种具有自适应功能的柔性叶片垂直轴阻力型风力机。对该风力机简化后,运用ANSYS软件对150 mm、250 mm以及350 mm三种不同弦长的风轮,在不同翅叶夹角下进行模拟计算,得出三种弦长风轮的平均转矩均在夹角为15°时达到最大,且在相同夹角时,弦长为150 mm风轮的转矩系数最大,波动最平缓,风能利用率最高。

A type of adaptive vertical wind turbine with flexible blade was proposed and designed on the basis of the traditional Savonius wind turbine.For the wind turbine simplified,using ANSYS simulated it with 150 mm,250 mm and 150 mm chord length under different leaf Angle.It showed that the average torque of three wind turbines were reached maximum when Angle of 15 degrees,and at the same Angle,the wind turbine with 150 mm chord length had the largest torque coefficient,the fluctuation in the most gentle,the utilization rate of wind power was highest.
